Despeckle
Occasionally small dots or specks appear in the background of a scanned image.
Remove unwanted speckles provides a cleaner image for OCR (Optical
Character Recognition) processing, and also helps to reduce compressed file
size.
Define the speckles (also known as image noise) you wish to remove by
specifying its number (size) and radius (range). The measuring unit is pixel.
The higher the number, the more speckles will be removed.
Before Despeckle
(noise number:0, noise
radius:1)
After Despeckle
(noise number:22, noise
radius:10)
Note:
The function is currently available for Black and White image only.
To scan at rated speed, it is recommended to set the noise radius up to 10
pixels.
